resolution of these challenges at any one point in time influences subsequent development on all of these challenges.
Erikson’s model has been criticized for its potential cultural specificity and its apparent rigid adherence to the perspective that maturation is based on developmental stages. Limited research supports both of these concerns: sequences are more fluid than depicted in the static framework such as summarized in Table A-1, and cultural groups do vary in the sequence of the particular tasks and challenges proposed (Berger, 1988). But in his more elaborated writings, Erikson himself repeatedly stressed the fluidity of his model, particularly in response to cultural variations in experience and norms. Despite these criticisms, the model is a useful way to think about the complexity of development.
